No contraption would be complete without these classic cogs! Spur gears, the simplest of all cogs make any creation go round. Spur gears, also called straight-cut gears, are teethed cylindrical discs. Adjacent gears set perpendicular to each other will catch in the paired gear's teeth and can be used to accomplish various mechanical tasks. Spur gears can also be stacked on top of each other.
Cut to any size, and made with scrap metal: there are no standard measurements in the post apocalypse! Strength varies with material. Can be combined with steel pipe and steam engine to create many contraptions.
